BOX-CAR.

Specification of Letters Patent.

P tented Apr. 16, 1918.

Application filed February 17, 1917. Serial No. 149,276.

To all whom it may concern:

Be it known that I, JOHN MONTGOMERY, of the city of Toronto, in the county of York, Province of Ontario, and Dominion of Canada, have invented certain new and useful Improvements in Box-Cars, and do hereby declare that the following is a full, clear, and exact description of the same. y

In railroad operation, boX cars are required to carry all kinds of package and loose merchandise, loaded and discharged with greater or less difiiculty, usually without regard for the property of the railway corporation or the requirements of the subsequent user.

As an instance of the above, a box car may be used for the carriage of: (a) steel rails, water pipes, large timbers, lumber, and the like which, owing to their length, are loaded and discharged through a small door placed at the end of the car; (b) machines and large crates which, owing to their weight and bulk, are loaded and discharged through the side doors; (0) grain or other loose merchandise, for the loading or' discharge of which, the operating conditions may require the use of either the side or end doors or both; and it has been ascertained in the field of actual use, in the'case of both inside and outside doors, that when fittings, no matter how small, even the head of a bolt or coach screw, are attached to the door post so as to obstruct the total width of the door opening, or, lessen the width of the car, by a fraction of an inch,the car will not be in operation many days before such fittings are broken oil, either during the loading and unloading of the freight, or by a shipper requiring the full width of the door opening, or'the full width of the car, and the car is thus disabled for the use of a subsequent shipper.

Inside doors, such as ordinarily used for grain-carrying purposes, heretofore stored, when not in use, beneath the car roof, are now impractical, not only for the above reasons, but also on account of their weight and size, and, the height of the car; and. outside doors are often blocked, by the load shifting in transit and binding against them, or by part of the load becoming so wedged between the door and the balance of the load, or between the door and the car body, as to prevent the sliding movement of the door when an effort is made to open it; and the car posts, are not'only injured during, the carriage, and, the loading and unloading, of the freight, but often become warped or bent, owing to the condition of the wood during the construction of the car, and under such conditions a grain door-cannot, as ordinarily built, be made to fit tightly against the door posts.

To overcome these and other diiiiculties in connection with the use of car doors, is the object of the present invention, which is attained, by constructing the door to operate on the ordinary outside sliding principle,

thus eliminating the use of fittings which would lessen the width of the door opening or the inside width of the car, by providing means to establish a grain-tight joint between the door openin and door, when the latter is closed and locked, so that'when the car is employed for grain-carrying purposes, there will be no leakage between the door and the car body, and toso' arrange this means that when unlocked the door will be permitted to swing outward clear of any obstructions which may become wedged between the load and the door or between the door and the car body.

Referring to the drawings Figure 1, is a fragmentary side elevation of a car and car door;

Fig. 2, is a fragmentary horizontal section on the line aa, Fig. l;

Fig. 3, is a fragmentary sectional plan of one of the'door posts and car door;

Fig. 4, is a detail sectional elevation. on the line Z)"-Z Fig. 3;

Fig. 5, is a detail sectional elevation, at

right angles to Fig. 4, of the parts shown in that figure;

Fig. 6, is a front elevation of the small door at the bottom of the main car door;

Fig. 7 is a horizontal section on the line co, Fig. 6;

Fig. '8, is a vertical section on the line d,cZ, Fig. 6; and,

Fig. 9, is a horizontal section through the small door at the top of the main car door.

A represents the top of the floor inside the car; B represents the car body, .13 represents a door way in the car body, C represents a stock sliding door track secured to the outside of the car body, above the door way; D represents stock door hangers; E represents a car door, suspended by the door hangers from the track; and 2 and 8 represent the car posts. 7

From the track C and the door hangers D, the car door is suspended to slide, as usual, close to the side of the car body until the door opening is closed or exposed, as the case may be; this movement in no way being interfered with by any of the additional features, hereinafter described, and no material change being made in the general .construction, .other than that the door has extra weight and is built stronger than formerly.

On both edges and the bottom of the door, strong metal sliding plates 8, 8 and .8 are securely but slidably'fastened, by means of special neck bolts 10 passing through the elongated slots 9, and made up tight by means of nuts 10, blind-mortised into the frame of the door, these fastenings occurring at intervals in the length of the plate.

Close to each of the slots?) is placed a metal rib 13, these ribs being secur ly riveted to the plates 8, 8 and 8*. Each rib 13 has an offset 13 as shown in Fig. 3, terminating in a wedge-shaped lug 14, the ofisets 13 permitting the lugs 1a to pass freely into holes 21 in the plates 19, 19 19"; see Figs. 3, i, and 5. Each neck .bolt 10 has a neck part 11 larger than the stem, and slightly less in diameter than the width of slot '9, and a head 1O larger than the slot .to overlap the sides thereof.

In assembling the parts, the shoulder 11 of the neck part comes to rest on a washer 12, and the bolt can thus :be made up tight, without causing the bolt head to bind or pinch the sliding plate 8.

Cooperating with plates .8, 8, and 8 are stationary metal plates 19, 19 and 19*, respectively,rabbeted into and secured to the car posts 2 and 3 and into the sill Z) just below the door opening, these plates 19, 19 and 19 being securely bolted in position with plow bolts 20. see Figs. 3, i and 5.

A section of these plates, 19, 19 19*, shows a lengthwise roove 25 and-flange 25, see Fig. 3, each flange having rectangular holes 21, see Fig. 4, with a wedgeshapedlip 22 projecting into one corner of each hole. A mortise is cutinto the post and sill opposite these holes of sufiicient size so that the lug 14: can move freely through the hole 21. The plates 8 and 8 have a length about equal to the height, and the plate 8 has a length about equal to the width of the door, the plates 19, 19 19 corresponding in length to the plates 8, 8 8 e v ct elv- The plates 8, -8, 8 are actuated by gneans of a lever 15 and bell cranks "1"? connected by links-l6 16, the parts 15 and 17 being pivoted to the car door by strong bolts 10 similar to the neck bolts 10. 7

To draw off that part of the car contents lying against the inside 'of' the car door and a hinge member 29. to enter between the,

hinge lugs 28*, the lugs 28 and 29" being bored for the hinge pin 29*.

The swing door 29 is provided'with a lug 29 .to enter between the locking lugs 28, the lugs 28 and 29 being bored for the locking pin 29, by which the door is maintained in its closed position.

The inner face of the door 29 is formed with a flange 29 parallel with its edges, and this flange enters a corresponding groove 28 in the metal frame 28, the purpose of the flange and groove being to prevent a leakage of grain between the swing door 29 and the frame 28' when the swing .door is closed and locked.

For loading the car to its full capacity and to provide an entrance for grain spouts, inspectors, shovelersiand the like, the top ofthe main car door E is formed with a door opening :1", and surrounding the inner side of the door opening, is a metal frame 132 having a metal tongue 32.

Hinged to the car door to close the door opening 1, is a swing door 32*, having a groove 32 to receive the metal tongue .32,

the swing door 32* being provided with the usual stock hinges 32 and lock .32

Operation.

loose merchandise, the door may be moved to close the door opening, and the lever 15 swung from Z to Y, and the sealing pin 23 may be inserted through the sealing clevis the lever in that position.

By moving the lever 15 from Z to Y, an important operation takes place, that is to say, the three sliding plates 8, 8", 8 are aa- 2.? and sealed with a standard seal, to hold tuated simnltaneouslyl As the movements of the three plates are identical, the move ment of one-is all that it necessary to describe; namely, the plate 8, shown on verse position to that shown in Figs. 1, 4, and 5. The position of lever 15 would be at Z and plate 8 would be at its highest point; the slot 9 would show nearly its full length above bolt 10, and the lug 14 would be in position 14 During the first stage of the movement from Z to Y, the lever 15' forces plate 8 downward and inward, the inward movement being caused by the shape of the slot 9, shown in Fig. 5 very little stress being required on the lever 15 until the angle in the slot reaches the bolt, on account of the freedom from friction of the plate 8 and lugs 14, as previously described.

When plate 8 has moved to bring the angle of the slot 9 to the bolt 10, the wedgeshaped lug 14 has moved from the starting position 14 to the intermediate position 14, and the inside edge of the plate 8 has entered the groove 25 in the plate 19, see Fig. 3. The lug 14 is then about to enter into contact with the wedge-shaped lip 22, the further movement of plate 8 being downward in a vertical line which brings the lugs 14 and lips 22 into actual contact. A strong pull on lever 15 at this time brings the lugs 14 and lips 22 into contact for their full length forcing the edge of the plate 8 deep into the groove 25 and straining the door, which is fastened to the plates 8, 8 8, by the neck bolts 10, along its vertical and bottom edges, toward the body of the car, and as these lugs 14 are placed at many points along the edges of the plates, the strain is such that close contact is secured with the car body, even if the door or post be warped or bent. When the end of the lever is secured under the pin 23, the lugs 14 and lips 22 will maintain this strain, while the car is in transit, and as efficiently as if the door were bolted to the sides of the car. I

In the past, many leaks were caused by slight defects in the wooden posts and car door, these defects rendering it impossible to make close contact ofthe door with the car body, but with the above-described construction, there is very little likelihood ofa leak occurring, as the entry of the plates 8, 8 and 8 into the grooves 25 is sufficient to not only form a grain-tight joint, but the metal fittings above described for the edges and bottom of the door and for the face of the door post will prevent these parts from being chafed or splintered ed.

The above-described doors are as applicable for use on steel cars as for wooden cars.

To prevent people from meddling with the lever when a loaded car is in transit, the clevis 27 is attached to the car in such a way as to turn up and receive the end of the lever, and, the sealing pin 23 has a chain attached to the eye atone end and to the car at the other, this pin projecting through the eye of the clevis, as shown, and having an elongated hole at its pointed end, suitable to receive a standard seal.

To release the car door,'the lever 15 is moved from Y to Z, actuating the plates 8, 8?, 8 to free the wedgeshaped lugs 14 from the wedge-shaped lips 22. The'door can then swing outward and thus be relieved from the pressure of'the load or obstacle against it, after which the door may be moved to its open position.

As the main car door may be constructed to abut against either the door post, orthe car body beyond the door posts, the term car body will be construed-to include-in its meaning those'structural parts of the car other than the car door, and the parts movable with it. v

In a box car, the combination of a car body having a doorway therein, a sliding door track secured to the car body, a car door to slide on said track and close or expose the doorway as the case may be, movable joint closing means along the bottom and both vertical edge faces of the door for establishing a tight joint between the car door and car body, locking means carried by the joint closing means, and means cooperating therewith, secured to the car body for straining the car door toward thecar body.
